Zincalume Flat Sheet 300mm
The Zincalume flat sheet is a 300mm wide strip of 0.55mm BMT Zincalume steel, cut to length for custom flashings and folding work. The wider strip suits bigger flashing profiles and capping pieces, and the unpainted aluminium-zinc finish resists corrosion without painting. It is priced per metre, cut to order with a +200mm / -0mm tolerance, and it is heavier than a standard 0.42mm roof sheet.

How To Use It
Cut the flat sheet to the length you need and fold it on a brake to make the flashing profile for the job. The wider strip suits larger profiles like apron flashings, capping pieces and edge trims. The 0.55mm BMT steel is formable yet stiff enough to hold its shape, and the unpainted finish needs no painting.
Applications
- Custom flashing profiles made on site
- Wider capping and edge trim pieces
- Zincalume roofs and coastal areas
- Where a non-standard profile is needed
What You Need To Complete The Job
Pair the flat sheet with a Zincalume apron flashing for a standard detail, and fix with Multifix roofing screws. For a wider strip see the 450mm flat sheet. Browse the Custom Flashing range for more.
